commit be4306ad928fcf736cbe2616b6dd19d91f1bc083 upstream.

Since

commit 890880ddfdbe256083170866e49c87618b706ac7
Author: Paul Kocialkowski &lt;paul.kocialkowski@bootlin.com&gt;
Date:   Fri Jan 4 09:56:10 2019 +0100

    drm: Auto-set allow_fb_modifiers when given modifiers at plane init

this is done automatically as part of plane init, if drivers set the
modifier list correctly. Which is the case here.

It was slightly inconsistently though, since planes with only linear
modifier support haven't listed that explicitly. Fix that, and cc:
stable to allow userspace to rely on this. Again don't backport
further than where Paul's patch got added.

<title>drm/tegra: sor: Do not leak runtime PM reference</title>

<content type='text'>
[ Upstream commit 73a395c46704304b96bc5e2ee19be31124025c0c ]

It's theoretically possible for the runtime PM reference to leak if the
code fails anywhere between the pm_runtime_resume_and_get() and
pm_runtime_put() calls, so make sure to release the runtime PM reference
in that case.

Practically this will never happen because none of the functions will
fail on Tegra, but it's better for the code to be pedantic in case these
assumptions will ever become wrong.

<title>drm/tegra: dc: Don't set PLL clock to 0Hz</title>

<id>urn:sha1:5b8f89685a9a4af58feb6a999af23933ce20df94</id>
<content type='text'>
[ Upstream commit f8fb97c915954fc6de6513cdf277103b5c6df7b3 ]

RGB output doesn't allow to change parent clock rate of the display and
PCLK rate is set to 0Hz in this case. The tegra_dc_commit_state() shall
not set the display clock to 0Hz since this change propagates to the
parent clock. The DISP clock is defined as a NODIV clock by the tegra-clk
driver and all NODIV clocks use the CLK_SET_RATE_PARENT flag.

This bug stayed unnoticed because by default PLLP is used as the parent
clock for the display controller and PLLP silently skips the erroneous 0Hz
rate changes because it always has active child clocks that don't permit
rate changes. The PLLP isn't acceptable for some devices that we want to
upstream (like Samsung Galaxy Tab and ASUS TF700T) due to a display panel
clock rate requirements that can't be fulfilled by using PLLP and then the
bug pops up in this case since parent clock is set to 0Hz, killing the
display output.

Don't touch DC clock if pclk=0 in order to fix the problem.

[ Upstream commit 41f71629b4c432f8dd47d70ace813be5f79d4d75 ]

idr_init() uses base 0 which is an invalid identifier for this driver.
The new function idr_init_base allows IDR to set the ID lookup from
base 1. This avoids all lookups that otherwise starts from 0 since
0 is always unused.

[ Upstream commit ef4e417eb3ec7fe657928f10ac1d2154d8a5fb38 ]

Though the unconditional enable/disable code is not a final solution,
we don't want to run into a NULL pointer situation when window group
doesn't link to its DC parent if the DC is disabled in Device Tree.

So this patch simply adds a check to make sure that window group has
a valid parent before running into tegra_windowgroup_enable/disable.

Commit Fixes: b9f8b09ce256 ("drm/tegra: Setup shared IOMMU domain after
initialization") changed the initialization order of the IOMMU related
bits but didn't update the cleanup path accordingly. This asymmetry can
cause failures during error recovery.

[ Upstream commit 24e64f86da40e68c5f58af08796110f147b12193 ]

The device tree bindings for the Tegra210 SOR don't require the
controller instance to be defined, since the instance can be derived
from the compatible string. The index is never used on Tegra210, so we
got away with it not getting set. However, subsequent patches will
change that, so make sure the proper index is used.

Pull drm updates from Dave Airlie:
 "This is the main pull request for 5.4-rc1 merge window. I don't think
  there is anything outstanding so next week should just be fixes, but
  we'll see if I missed anything. I landed some fixes earlier in the
  week but got delayed writing summary and sending it out, due to a mix
  of sick kid and jetlag!

  There are some fixes pending, but I'd rather get the main merge out of
  the way instead of delaying it longer.

  started landing tigerlake support, lots of icelake fixes and lots of
  locking reworking for future gpu support, lots of header file rework
